摘　　要：空间数据共享在GIS领域中越来越受到重视,它可以有效的解决不同行业和部门之间的重复投资和信息资源浪费.GIS互操作是实现空间数据共享的必由之路.本文描述了空间数据共享的方法、面临的问题,由此介绍了GIS互操作的概念.着重介绍了GIS互操作的含义、互操作的类型、以及实现的方法;简述了开放地理信息系统协会(OGC)制订的OGC规范所包含的基本内容.Spatial data sharing is more and more being paid attention to in GIS field, it can effectively solve overlapping investments and the waste of information resources between all kinds of departments. GIS Interoperability may be the only way to implement spatial data sharing. This paper describes the methods of spatial data sharing and problems faced, therefore has introduced the concept of GIS Interoperability. This paper emphasizes characteristics and the types of GIS Interoperability and the method of implement GIS lnteroperahility. It also simply introduces the basic content of Open GIS Consortium Soecification.
